One of the clearest available introductions to variational methods, this text requires only a minimal background in linear algebra and analysis. It explains the application of theoretic notions to the kinds of physical problems that engineers regularly encounter. Many helpful definitions, examples, and exercises appear throughout the book. 1975 edition.
Very good engineering oriented examination of Lagrange and Hermite polynomials leading up to splines including their uses in collocation and the Rayleigh-Ritz finite element method. Includes mesh-generation for two-dimensional boundary value problems and interpolations. Too bad this author only wrote this book. Lots of examples and pictures.
